APPLICATION OF INTEGRATED ELECTRONIC CONTROL SYSTEMS WITH RENEWABLE SOURCES AND STORES OF ENERGY IN THE MINING INDUSTRY

The use of modern combined power plants CASE with renewable (alternative) sources and energy storage allows to increase ecological safety, energy efficiency and reduction of diesel fuel consumption in the mining industry. To achieve these goals, the modernization of power supply systems of mining companies in the first place, far from the high-voltage electrical networks that feed at the present time from the Autonomous power plants with alternately operating diesel generator sets. In the present CASE are encouraged to incorporate renewables and energy storage. As renewable energy is preferable to use widespread wind generators and solar panels as storage devices – batteries and supercapacitors are capacitors with a double electric layer CDAS. Modern CASE needs to ensure the acceptance of regenerative energy and independent electricity supply and be fitted with a reversible power electronic converters for IGBT transistors or conventional thyristors. Also discussed ways to improve the efficiency of mining locomotive transport by applying CASE and increase the accuracy of calculations of coefficients of adhesion given the abrasiveness of rocks. The proposed technical solution will significantly improve the energy efficiency and environmental safety, to reduce electricity consumption by locomotive transport by 15–20%, diesel fuel consumption at least 3–5 times.
